Blu-ray XL, or BDXL, is the next specification for the optical storage format, as it was released just now by the Blu-ray Disc Association. BDXL is now available for licensing and the specifications include a maximal storage capacity of 128GB.

The current Blu-ray format can only store up to 50GB, officially, using dual layers of 25GB each. The new BDXL specifications takes the multi-layer technology to a whole new level with three or four layers for 100GB or 128GB.

The BDXL specification, which is targeted primarily at commercial segments such as broadcasting, medical and document imaging enterprises with significant archiving needs, will provide customers with write-once options on 100GB and 128GB capacity discs and rewritable capability on 100GB discs.

The new BDXL format specifically targets market with demands for lots of storage capacity, but it will require new media and more powerful lasers to burn and read the new discs. Unfortunately this means that current Blu-ray units will not be compatible with the new formats.

When and if BDXL finds its wait into retail is so far uncertain.
